Very clean setup, well done....but for future people looking, this and most other "mods" replacing the chain return, while most are very well done, most if not all defeat the design purpose of the chain/spring return for the powder measure in the first place.... which is safety.....using the chain return there is no way you can double charge a case if you short stroke the press....

This setup also accomplishes the same ass the chain setup, only more reliably. I chose it over the spring return setup for that reason. I just got this press and not used to it yet, so I wanted to keep the chance of error to a minimum.

if you look in your case you want overcharge or under. I got that crap out of my way.

Heres is the best loadmaster, a LLM decapping machine. Dont know who was first to think of it,, prob john lee. S Rowe helped me remember and set it up. It does all my pistol (i shoot pistol only). A gallon pretty quick plus mouth straightened out (slight pre-expansion), counted, found splits, find bad base rims, & each piece of brass has been thru loadmaster before washing and bb'ing. So they go thru LLM really smooth second time when you start to load in any machine. l like prepping brass, hav to, l pick up alot of range brass.

"Note: there is an option with this system that eliminates all chains."

What is this option? I have that powder drum and I see no way to make it chainless.

Not real sure what your question is.

If you are referring to the Auto Drum measure, per its instructions, it may be run with chain reset of disconnect , manual finger push reset of disconnect (chainless) or removal of the disconnect all together (chainless) so it dispenses every time it is actuated (is possible to double charge)
